Base station assisted information centric network

Abstract

System and techniques for base station assisted Information Centric Network (ICN) are described herein. A mobile network base station receives an ICN packet from a user equipment (UE). The mobile network base station identifies an aggregate packet data unit (PDU) session with a user plane function (UPF) ICN gateway (ICN-GW) hosted in a mobile network core network (CN) for the ICN packet. Then, the mobile network base station transmits the ICN packet via the aggregate PDU session.
